Other Parts Discussed in Thread: ADS54J40
Hello.
I simulate LVPECL output LMK04828 for ADS54J40 in Hyperlynx, and get a bad result, when termination includes capacitors. Without them, the signal is normal.
termination with capacitors.
without capacitors
Also, I met different termination options:
with capacitors near LMK and near ADC, or only near LMK. 100 Ohm resistors before or after capacitors
I do not understand all the subtleties, and I would like to ask - which option is best for connecting to ads54j40. Can i use HSDS output?
